摘要

In order to looking for the fault of rock drilling hydraulic pump, the data of pressure and flow can be collected, from which wavelet analysis was used to find characters of the fault. So a new rock drilling pump fault diagnostic model by SVM was based on the energy value of the data deal with wavelet analysis. The results of regression show that the accuracy rate of SVM2 was higher than SVM1, and different core functions can get different regression accuracy from which RBF core function was better than others.
